DuPont Fluoropolymer Solutions has announced the commercial availability of a new perfluoroalkoxy-based resin for insulation of wire, cable and intricate electronic parts. The new fluoropolymer resin, DuPont™ Teflon® PFA 416HP, features a high melt-flow rate while maintaining very good MIT flex life.

These characteristics offer coaxial wire manufacturers, semiconductor OEMs and electronic device designers the ability to coat ultra-thin gauge wire and to injection-mold fine, intricate thin-wall parts in a more efficient manner than can be done with other fluoropolymers. DuPont™ Teflon® PFA 416HP resin provides all of the advantages of PTFE – including ultra-high thermal resistance and dielectric properties – and combines those critical attributes with a very high melt-flow rate.

These inherent characteristics enable almost transparent coatings on ultra-fine wire, such as the kind used in mobile telephones, medical sensor wires, micro coaxial cables, and wireless antenna applications in headsets, laptops and smart phones. Teflon® PFA 416HP also provides excellent chemical resistance, very good stress crack resistance and easy flow for molding applications. “Our new PFA resin is a breakthrough, high-performance product innovation that opens up even more options for fine wire applications where maximum flexibility and high thermal resistance are needed,” said Jacob Lahijani, Ph.D., senior technical consultant – DuPont Fluoropolymer Solutions.

“Ultra-high thermal resistance in insulation means that highly intricate electronics can be insulated with an extremely thin, almost transparent coating and still withstand soldering. With the higher melt-flow rate, this new resin broadens the ability to injection-mold fine, intricate parts as well.” DuPont™ Teflon® PFA 416HP is ideally suited for applications such as antennae for wireless electronics, medical probe cables, micro HDMI cables, internal wire harnesses for electronics, and other uses where high melt-flow rate, very low viscosity and high stress crack resistance are critical.To obtain product information and learn more about applications for PFA resins, visit www.dupont.com/416HP.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
